Global SMS – Sending SMSes in node.js

Hi…

here is a short intro into how to send a SMS by using Global SMS service of Developer Garden. I already gave a short intro to our OAuth service. You might want to have a look there to find how to resolve the credentials. Also, if you want to extend or play around, have a look at the documentation.

Update: Please be aware that there are different plans available (aka BASIC and Premium). They offer different services, as you can see in the table below.

 

 

As you can see, not all features are available in the BASIC model.

I made basically two files for node.js. The first one takes care on the OAuth part. You can find the source here (please see also update below):

All it does is to provide a functionality to acquire a client access token from the OAuth server. I am using callbacks here since we have to wait for the server to answer.
The rest is pretty straight forward.

What this file does is, first of all to get the OAuth handler described in the source above assigned. We are calling then and using the OAuth client token to build a valid header. We then build the JSON body which is shaped in an interesting fashion but at least GSMA conform (adhere global standards whenever you can). All in all, I think the code is quite self-explanatory.

The answer is something like this:

Some remarks:

  • If you have no validated sender number, use 0191011. You do not need to use the tel: prefix then.
  • In the documentation the environment is called basic. This is a bug, you need to give budget instead (we are currently fixing that).

 Update:

On some Windows implementations, the options of the request need some additional parameters (as marked below):

The first one is to switch off the global HTTPS agent, the second is to accept any SSL certificate which by the way is requested by the last new line.

We made the experience that node.js uses different default protocols. Therefore, by explicitly asking for SSLv3 you make sure it uses the right one. This was necessary on our Windows Vista based test system.

Have fun.
